ACETYLENE-G-AS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 753,632, dated March 1, 1904.

' Application filed June 19, 1902. Serial No- 1l2,28'7. (No model.) i

To (all whom it may concern.-

Be it known that I, EDWIN M. ROSENBLUTH, of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Acetylene-Gas-Generating Lamps, whereof the following is a specification, reference being had to the accompanying drawings.

My invention relates to generators of the general class wherein the supply of water gravitates to the supply of carbid, and my improvements may be employed with particular advantage in lamps and similar portable generators.

It is an object of my invention to provide a magazine-lamp whose casing supports a plurality of separately-removable carbid-receptacles which may be interchangeably connected in operative relation with a water-receptacle and a burner, which latter are mounted in said casing.

My invention comprehends the various novel features of construction and arrangement hereinafter more definitely specified and claimed.

In the accompanying drawings, FigureIis a perspective view of a vehicle-lamp conveniently embodying my invention. Fig. II is a longitudinal sectional view of saidlamp, taken on the line II II in Fig. III. Fig. III is a transverse sectional view of said lamp, taken on the line III III in Fig. 11.

The lamp shown in said figures comprises the casing whose cylindriform body 1 is supported by the vertical standard 2. The water-receptacle 3 is mounted in stationary position within said casing-body 1 in registry with said standard 2, and the bottom of said water-receptacle 3 is provided with the cap 4, whose screw-thread 5 is fitted to the corresponding screw-thread 6 upon the carbid-receptacle 8. Said carbid-receptacle being provided with the flange 9 and gasket 10 may be removably sealed in operative relation with said cap 4. The water-conduit 12 opens from said water-receptacle 3 through the cap 4 into the carbid-receptacle connected therewith and is provided with the controllingvalve 13. The stationary section of the gasconduit 15 extends from the top of said cap 4 through the water-receptacle 3 and terminates.

above the top of the casing 1, where it is o'pposed by the stationary conduit-section 1'6 and is connected therewith by the removable flexible section 17, which contains the filtering medium 18. The lower extremity of said gas conduit section 16 projects through the side of the standard 2, as shown in Fig. II, and terinmates in the vertical member 19, which is provided at its top with the burner 20, within the casing 1, in front of the water-receptacle 3, and said gas-conduit is provided between said standard 2 and the burner 20 with the drip-outlet 22, normally closed by the removable screw-plug 23.

The diaphragm extends across the casingbody 1, forming a flame-chamber 31, inclosing the burner 20 and separating the latter from the water receptacle 3. The concave surface of said diaphragm being polished it serves as a reflector behind the burner 20.

The casing 1 is provided at its front extremity with the door 33, which is hinged at 34 and provided with the transparent panel or lens 36, which may be removed and replaced through the opening 37 in the top of the door, which opening is normally closed by the semicircular .band 38, hinged at 39 upon 'the door and provided at its free extremity with the hinged hasp 41, which is engaged by .the turn-button 42, as best shown in Fig. I.

Said door is normally retained in closed position by the spring-catch 43, mounted upon the casing 1. v

As shown in Fig. II, the casing 1 is provided with air-inlets in the bottom of the flame-chamber 31 and the chimney 46, at the top thereof. Said casing is also provided-with a series of air-inlets 48 behind the diaphragm 30 and between the latter and the water-receptacle 3 and air-vents 49, adjoining the car bid-receptacle 8, and conveniently located in the sides of the standard 2. r 1

On the top of the Water-receptacle 3 is mounted the magazine 51, which opens through the top of the casing 1 and is conveniently provided with the lid 52, which is hinged to the magazine at 53 and provided with the fastening device 54. Said magazine is arranged to hold a plurality of separate carbid-recepta-' IOO cles 55,which are adapted to be interchangeably connected with the screw-cap & upon the bottom of the water-receptacle 3, but are normally closed by respective screw-caps 56.

Adjoining the magazine 51 is the tubular sheath 58, which rigidly connects and braces the water-receptacle 3 in said casing 1. 'Said sheath removably supports the implement 59, which may be conveniently utilized to clean the carbid-ash from the receptacles 8 and 55.

The magazine 51, gas-filter, and the cleaning implement adjoining the same are conveniently inclosed by the hood 61, which is hinged upon the lamp-casing at 62 and provided with the fastening device comprising the slide-bolts 63. The rear wall of said hood 61 is provided with vents 64, so that air is permitted to circulate therein. The handle 65, which is fixed upon said hood 61, serves as a convenient means for manipulating the lamp.

Said gas-conduit 19 is surrounded by the wind-shield 66, which supports it in rigid relation with the casing l, and the front of said wind-shield is perforated at 28 and the back thereof is open, surrounding the gas-conduit 16, as indicated in Fig. II, to permit free circulation of air.

The lamp-casing is provided upon its opposite sides with the sockets and set-screws 71 to conveniently engage a supporting-bracket.

The casing-standard 2 comprises the door 7 2, which is hinged at its bottomupon the wire frame 7 3 and provided at its top with the fastening device comprising the slide-bolt 74:. Said door 72 affords convenient access to the carbid-receptacle, which is in operative connec tion with the water-receptacle 3 and permits the manipulation of the Valve 13, controlling the water supply, which latter is conveniently introduced to the receptacle 3 through the tube 75, normally closed by. the cap 76, provided with the vent 77.

It is to be understood that the carbid-receptacle 8, containing the charge of carbid 78, being in operative connection with the waterreceptacle 3 and the burner 20, said charge may be consumed by the admission of water through the valve 13, and thereupon one of the separate carbid-receptacles upon the magazine may be substituted for the receptacle 8, and so on, until all of the carbid-receptacles supported by the lamp structure aresuccessively utilized in interchangeable operative connection with said water-receptacle 3 and burner 20. The filtering medium 18 within the removable section 17 of the gas conduit serves to retain objectionable matter carried by the gas, and any condensation from the latter gravitates to the drip-outlet 22 and may be conveniently discharged therefrom. Said removable section 17 is conveniently formed of a cut length of flexible rubber tubing'and may be withdrawn and recharged with filtering material 18 when desired. It is to be noted that the arrangement is such that if the gas generated should accidentally accumulate within the lamp at an abnormal pressure such pressure would suffice to detach said removable section 17 instead of rupturing any other portion of the lamp structure.

It is to be understood that I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention.
